RAISIN-SEEDER.

SPECIFICATION forming part of Letters Patent-No. 591,322, dated October 5, 189'?. Application Hed matthew/,1896. serial No. 613,593. or@ modem To all whom, t may concern:

Be it known that I, JOHN WILSON BROWN, J r., a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Raisin-Seeders, of which the following is aspectication.

My invention relates to certain improvements in raisin-seeders, for which Letters Patent were granted on the 2d day of April, 1895, No. 536,778.

The object of my invention is t0 cheapen the manufacturey of the machine and to so construct it that it can be dismembered for cleansing and put together again without the liability of the parts not registering.

A further object of the invention is to provide means for adjusting the presser-roll toward and from Athe seeding-roll.

In Inachines of this class, which are used mainly in the household, the parts must be so arranged that thermachine can be dismantled for'cleansing and put together without having to readj ust the parts. The great difficulty heretofore experienced with raisinseeders of this class has been that they must be set absolutely correct, otherwise they will not properly seed the raisins. Consequently these raisin-seeders have performed the Work satisfactorily at first, but, as they must be constantly cleansed, the parts in time do not register and the machine has to b e discarded.

Referring to the accompanying drawings, Figure l is a perspective view of my improved raisin-seeder. the head with the detachable parts removed. Fig. 3 is a section on the line 3 3, Fig. 4. Fig. 4 is a view looking in the direction of the arrow, Fig. 3. Fig. 5 is a section on the line 5 5, Fig. 3. Fig. 6' is a section on the line 6 6, Fig. 3, with the .seeding-roll removed. Fig. 7 is a View of the seeding-roll detached. Fig. 8 is a detached sectionalview of the presserroll, and Figs. 9 and 10 are views of a modiflcation.

A is the head of the device, connected toa clamp A in the present instance by a curved neck A2. This Sclamp is constructed in the ordinary manner and is adapted to be secured to a table, shelf, or other fixture. The head A is arranged to overhang the table, so that a .semble them out of line.

Fig. 2 is a perspective view of bowl or other vessel can be placed thereunder to receive'the meat of the raisins.

avis thehopper, a' the side plate, and a2 a curved back plate. Extending from the side plate a' is a spout d3, having flanges a4 at each side. `.This spout is an integral part of the cast head A.

B is the seeding-roll, and D is the presserroll. The seeding-roll B is made as shown in Fig. 7 and is adapted to a stud A3, permanently fixed t0 the head A. present instance projects from the side plate a', which is thickened, so as to form a rigid support for the stud. The stud can be secured to the head either by casting the head around it or by riveting it to the head after it is in proper position. The central line x of the stud must bear a xed relation to the inner edge 0c ofA the spout as, Fig. 6, so that when the seeding-roll is slipped onto the stud its relation to the spout will be fixed, so that no matter how carelessly the device is taken apart and put together it is impossible to as- This is accomplished, therefore, by making the spout, spindle, and head a unit, as shown clearly in Fig. 2. It will be seen that the roller is supported throughout its length by the stud, which is rigidly xed to the frame, and overcomes the objectionable overhanging feature found in other seeders, and the stud being permanently fixed tothe side plate overcomes agreat difflculty in raisin-seeders as heretofore made, where the rotating shaft was journaled in a side bearing, making the structure weak and permitting an uneven and wabbling motion of the 'shaft after the least wear upon the bearing.

The stud in the,

The lower portion of the hopper t is shaped to conform to the rolls B and D, and the back Aplate a3 of the casing is curved to conform to the roll.

The seeding-roll B is made up of a series of plates b, which alternate with washers b', mounted on the sleeve b2.

This sleeve has a the blades are confined between the head h3 of the sleeve and the handle. The blades b are serrated in the present instance,somewhat similar to saw-teeth, so that they will puncture the raisin, and they are so spaced that the meat alone will enter the spaces between the blades while the seeds are held on the periphery. In the present instance loosely hung between the blades are doffers e, each of which has a projection c extending beyond the periphery of the roll B and into the space between the curved back plate a2 and the rear end of the spout CL3. These dofiers are for the purpose of extracting the meat of the raisin from between the blades after the seeds have been scraped off the face of the roll by the rear edge ofthe spout a3. The roll B is loose on the spindle A3 and is prevented from moving longitudinally thereon by a cotter d5 0r other suitable fastening.

The inner end of the spout c3 is preferably turned up, as shown in Fig. 3, to form a comparatively sharp edge to act as a scraper, so that it will more readily remove the seeds from the periphery of the roll B.

Directly in front of the roll B is the presserroll D, made in the present instance of rubber or other elastic material, and this presserroll is so adjusted in respect to the seedingroll B that as the raisin passes between the two rolls the meat of the raisin willbe forced into the spaces between the blades, while the seeds will be embedded more or less into the yielding surface of the roll D. This roll in the present instance is made, as shown in Fig. S, of a spool d, preferably having flanges CZ at each end, and over this spool d is passed a rubber sleeve d2, preferably recessed at each end to receive the flanges d of the spool. The spool is mounted on a spindle E, which has a head e at one end and screw-thread at the opposite end. The spindle is adapted to the arms e of a lever E, hung at e2 to a bearing a6, in the present instance formed on the face of the hopper a. This lever E has an arm e3 projecting beyond the pivot e2, and adapted to this arm is a set-screw e4, which bears against the hopper. By 'means of this set-screw the roll can be adj usted toward and from the seeding-roll B. This adj listing-lever can be modified without departing from the main feature of the invention, which feature is to provide an accurate means of adjusting the presser-roll and to fix the roll in the adjusted position.

The operation of the machine is as follows: The roll D is adjusted in respect to the roll B, as above described, so that as the raisins, which are inserted in the hopper, are drawn between the rolls by the turning of the roll B in the direction of the arrow, Fig. 3, the meat of the raisins will pass into the space between the blades `of the roll B, while the seeds will remain on the surface, and as the roll B revolves the seeds will be scraped oft by the edge of the spout as and be directed into a suitable receptacle, while the meat will pass the spout and will be discharged by the doffers into a receptacle under the machine.

To cleanse the machine after seeding the raisins, all that is necessary is to draw the cotter a5 and remove the roll B with the handle B from the iixed spindle A3 and cleanse this roll. The other parts of the machine can be readily wiped off. After the roll is cleansed it can be again placed on the spindle and the eottcr returned to its proper place and the machine will be in accurate working order, as the relative position of the spindle and hopper is fixed. In some instances the machine may be cleansed without removing the roll B.

In Figs. 9 and l0 I have shown the roll D of yielding material mounted on a stud f, secured to the side of the head by a wing-nut f. The stud has a sleeve f2, adapted to a slot in the frame of the machine, so that upon loosening the wing-nut the roll D can be moved toward or from the roll B.

I claim as my inventionl. As a new article of manufacture the frame of a raisin-seeder, having the dischargespout formed'integral therewith and having a spindle fixed thereto for the reception of the 'seeding-wheel, the spindle and spout being rigid in respect to each other so that when the machine is dismelnbered for cleansing the relation of the spout to the spindle cannot be altered, substantially as described.
